Di?nejisio»s. — 4.5 x 1.5. 



Habitat. — Brisbane, Queensland (H. Hacker). 



Two specimens examined (sex ?). It can readily be distinguished 

 from flavus by its smaller size, black underside and antennae, and 

 the short, thick joints of the last. There may be a doubt' as tt> 

 whether this insect may not require separate generic rank, but 

 at present the combination of pointed mandibles, obeonie prothorax,. 

 widely separated eyes, justifies its inclusion under atoichus.
